Exclamation mark at my signal bar but its showing that there is signal
Hi looking for some help. I have just switched to ID mobile and transferred my number over. I received a text saying that the number had been switched however, I cant make or receive calls as my signal bar has an exclamation mark on it. I have reset the phone, turned airplane mode on and off. How do I sort this as I go away tomorrow and need my phone when I am away.
